If a client connects (samba 3.0.14a) to a samba share and transfers large amounts of data for several minutes then the file server (barc) stops responding to the client and doesn't respond to pings.  The console (vga text mode /w/ PS2 keyboard) also stops responding to the keyboard.  The only way to recover is to reboot using the PC's front panel reset button.

Shoud not be related.
For the record, I have several file servers using raidframe raid-1 volumes,
and none shows this behavior. They are still running 1.6.2_STABLE. I use intel
gigabit network cards, and and HPT370 adapter (for the IDE-based ones).
Can you reproduce the hang by doing only disk I/O, or only networks I/O ?
Can you post the dmesg ?
